FWIW, we installed a splicing kit at our site last summer to replace a piece of damaged 7/8. The loss was negligible, especially compared to what it would have cost us to replace an additional 250' of helix.
If money were no object, I'd go for a brand new mother-run of 7/8, but since they do call this AMATEUR radio, sometimes we've got to accept the next best thing.

(We already tried CSI: Cedar Rapids but it didn't do well with the audiences -- they fell asleep.) Maybe Kevin or Scott could be called in as "expert witness" special guest stars? And of course, all radio sites will have to be dark, so even mid-day the investigators will have to look around with powerful flashlights to find that "one clue they missed at the scene when they were there two days ago".

Amphenol actually does make a (relatively expensive) hardline splicing kit. Works well, according to the club techs who had to use one once on one of our runs of 7/8 that was damaged. > I actually have a question here about loss.

If you can't do new feedline for the whole run, get a splicing kit and not connectors. Better yet, consider it part of the "cost of moving" and don't move if you can't replace the line. That'd be my "take" on it. Build to commercial standards, or don't build... you'll only be back later fixing it... like anything else "hammy" I've ever seen/dealt with. But we all here understand the reality of budgets, or lack thereof... (sigh)... Nate WY0X
